Beam hanger



June 3, 1930. c. M. COPELAND BEAM HANGER Filed July 13, 1927 INVENTOR Em: M-Enp Bland X ATTORNEY Patented June 3, 1930 UNITED sra'ra cLnvT M. cornmnn, or MARLAND, OKLAHOMA A BEAM HANGER Application filed July 13,

This invention relates to for oil wells and the like. The primary object of the invention is to provide a beam hanger which will provide a substana beam hanger tially straight pull on the sucker rods dur ing a pumping operation. The sucker rods are operated from a walking beam. Since the toe of the walking beam swings in an are, there is a tendency for the hanger to swing in an are, particularly on the upstroke and throw the rods against the tubing. My invention contemplates a hanger which will insure a substantially vertical pull of the rods during the upstroke of the walking beam and which will maintain the vertical moveinenton the down-stroke.

The novelty of the invention will be better understood by reference to the following description in connection with the accompanying drawings in which:

2 lines and thereof to receive the 7 Fig. 1 1s a side elevational view of the hanger applied to the forward or toe end of the walking beam, the two extreme'positions of the walking beam being shown in dotted Fig. 2 is a front view of the hanger and the end of the walking beam.

The walking beam 1 is of usual construction with notches2 and3 at the toe end trunnions 4 and 5 of the hanger. A loop or eye 6 is carried by the trunnions so that the hanger can be lifted to apply it and to remove it. The usual plate 7 may be used for holding the trunnions in place. The trunnions are really the ends of a rock shaft from the center of which is hung a rod 8 having a rearwardly projecting rod 9 extending at an acute angle in an upward direction with an upwardly and forwardly extending portion 10 forming an elbow 11. The upper end of the extension 10 is connected to the rod 8 by a transverse portion 12. The portions 9, 10 and 12 can all consist of a single rod welded to the rod 8, the whole forming a frame in the notch or slot 18 with the elbow ll resting against the end 14 of the slot 13 as shown in Fig. 1. At the lower end of the rod 8 is a tranverse hanger shaft 15 from which are suspended two rods 16 and 17 'taining the lower end 20 of 1927. Serial No. $5,386.

loosely mounted upon the cross-bar or shaft 15 and connected at their lower ends by the cross-bar 18 which carries the polish rod 19. The elbow 11 serves as a cam for mainthe rod 8 in a fixed vertical plane during the up-stroke of the walking beam 1, sothat the frame consisting of the members 15, 16, 17 and 18 will rise in a straight vertical planeto pro vide a substantially straight vertical pull 1 011 the sucker rods The pull is not in a true straight vertical plane because the camming surface 11 is constantly adjacent to the same point in the base of the groove atthe end of the walking beam causing the point 15 to move in a slightly arcuate path, but the swing of the end of link 8 is only about one and one-half inches ina five foot stroke so for all intents and purposes, it can truly be said that the movement of the end of the link 8 is substantially in a vertical plane. On the down-stroke, the weight of the rods will cause them to move in the same vertical plane, therefore, liability of the rods moving out of vertical plane will be eliminated. The offset angular portion of the hanger formed by the members 9, 10 and 11 form an elbow which bears against the end 14 of the slot 13. The angle of the elbow riding on the end 14 maintains the rod 8 in a substantially vertical line during the swing of the walking beam and thereby insures a direct vertical pull on the sucker rods.

What I claim and desire to ters-Patent is:

1. A beam hanger comprising a rod having means for attachment to a walking beam having a slot in its end, a rearwardly projecting elbow-shaped camming portion on the rod to bear against the base of the slot in the walking beam the rod to a polish rod.

2. A beam hanger comprising a rod having means for attachment to a walking beam having a slot in its end, a rearwardly projecting offset elbow-shaped camming portion on the rod to bear against the base of the slot in the walking beam, means for attaching the rod to a polish rod, said means com prising a hanger frame loosely connected at secure by Letand means for attaching its top to the first named rod and means on the lower end of the rod for attachment to a polish rod.

8. A beam hanger comprising an irregular shaped body having an angular oflfset portion adapted to bear against the base of a slot in the end of a walking beam and an end portion to engage a notch in the walking beam so that the lower end of the body portion will travel in a substantially vertical plane during the upward swing of the forward end of the walking beam.

4:. A beam hanger comprising an irregular shaped body having an angular ofiset portion adapted to bear against the base of a slot in a walking beam and an end port-ion to engage a notch in the walking beam so that the lower end of the body portion will travel in a substantially vertical plane during the upward swing of the forward end of the walking beam and a polish rod supporting frame loosely fastened to the lower end of the body portion.

5. In combination, a walking beam having a longitudinal slot in its forward end and a beam hanger comprising a straight rod, trunnions suspending the straight rod from the walking beam and an angular oiiset portion carried by the rod for engagement with the walking beam in the rear end of the slot so that the lower end of the straight rod will travel in a substantially vertical plane durin the upward swing of the walking beam.

in testimony whereof I aflix my signature.
